METHOD FOR MEASURING DRIVE LIFETIME OF ORGANIC EL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for stably measuring the drive lifetimes of a plurality of organic EL devices.

SOLUTION: In a method for measuring the drive lifetime of an organic EL (electroluminescent) device, the drive lifetime of an organic EL device is measured in a state where wind with a constant temperature is blown toward one or a plurality of organic EL devices while a direction of the wind is changed.
